Genesis 27:3-5, 40

So take your bow and arrows and go hunting in the field for an animal for me to eat. When you prepare the tasty food that I love, bring it to me, and I will eat. Then I will bless you before I die.” So Esau went out in the field to hunt. Rebekah was listening as Isaac said this to his son Esau.

You will live by using your sword, and you will be a slave to your brother. But when you struggle, you will break free from him.”
